The Ocean's Billion-Ton Carbon Removal Opportunity | Gigablue

What if the cheapest, largest carbon removal machine on Earth isn't a factory, but phytoplankton in the ocean?Company bio:Gigablue is building MCFS (Microalgae Carbon Fixation and Sinking), a marine carbon removal method that uses phytoplankton and carbon carrier pods to capture and store carbon in ocean sediment. They recently raised a $20M Series A to scale their work. Speaker bio:Ori Shaashua is the co-founder of Gigablue and a serial technology entrepreneur, investor, and executive with a multi-sector track record across artificial intelligence, climate tech, cybersecurity, digital health, and smart mobility.Five lessons for climate entrepreneurs:Build for the real bottleneck, not the obvious one – In carbon removal, the challenge wasn’t just capturing carbon; it was exporting it durably. Great founders identify the true constraint and design around it.Trust is part of the product – In a market that depends on verification, transparency, and public credibility, open methodology and measurable outcomes become strategic advantages.Use the business model buyers already understand – Gigablue borrowed contract structures from commodity and energy markets, making it easier for large buyers to transact with confidence.Scale requires timing, not just ambition – Ori emphasized that the market is moving from experimentation to consolidation, and that entering at the right stage can lower risk for both founders and buyers.Tie the mission to durable economics. – A climate solution has to make financial sense, not just scientific sense. The strongest ventures are built where impact and commercial viability reinforce each other.--1️⃣ Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.
